The objective is the development of oxidation protective coatings for vanadium-base alloys for use at 1800 to 2500 F. The effect of the pack siliconizing process on the mechanical properties of .020 inch thick sheet of V- 60 wo Cb - 1 wo Ti is being studied. Samples are being evaluated before and after various high temperature exposures. Development of an oxidation resistant slurry or liquid cementation type coating for V-60 wo Cb - 1 wo Ti is progressing. Five slurry compositions containing tin, silicon, silver, copper, aluminum, and columbium were investigated, and several of these showed good coverage, even at corners and edges.
